$act=$_GET[act];
$product_id=$_GET[prcid];

if($act=="add")

$cars_id=explode(",",$_COOKIE[buypro]);
//echo "
";<br>  	//print_r($cars_id);<br>	//echo"
Copy after login
";
//exit;
foreach($cars_id as $pr_id)
{
if($pr_id==$product_id)
{
echo "<script>alert('您已经购买了此商品,请查看购物车!');location.href='car.php';</script>";
exit;
}
}

if(empty($_COOKIE[buypro]))
{
setcookie("buypro",$product_id,time()+3600);
setcookie("buycount","1",time()+3600);
}
else
{
$newpro=$_COOKIE[buypro].",".$product_id;
$newcount=$_COOKIE[buycount].","."1";
setcookie("buypro",$newpro,time()+3600);
setcookie("buycount",$newcount,time()+3600);
}
}
//删除
if($act=="del")
{
$buy=$_COOKIE[buypro];
$cars_id=explode(",",$buy);
$buycountary=explode(",",$_COOKIE[buycount]);
$newid=array();
$carcount=array();
for($i=0;$i {
if($cars_id[$i]!=$product_id)
{
$newid[]=$cars_id[$i];
$carcount[]=$buycountary[$i];
